A step into the unknown

I began to walk down the street trying to look as busy as possible. As if I knew where I was going. I had no idea it would be so hard to pretend that I knew my destination. Was that police officer still following me? I didn't want to look back because I was afraid I would make him even more suspicious. Then I used my favorite maneuver. I stopped  and tapped my shoe on the ground as if something got into it. Then I bent down, took my shoe off and shook it a few times like there was a pebble in it or something. When I was bending down, I managed to check if the police officer was still there. He was! On my side of the street, talking on his radio. I put my shoe on and looked up at the building at which I happened to stop. It was tall and bright, one of those downtown glass and steel beauties. Well, this was it. It was my "destination." No way, I'm going to show that police officer that I didn't know where to go. I decisively walk up to the building and grabbed the heavy metal door handle.
